Why did this just happen ?


Folks ,

I have been using an old (2012) iMac with a 1TB SS drive for years. It is connected to an old Benchmark USB DAC that feeds my refurbished(2X) Audio Research SP IX mark 2 preamp into my Quicksilver KT88 mono blocks that feed my Pro Ac SE’s. 

I just bought a used 2020 MacBook Pro($400.00) to replace the old iMac. I connected it to my USB DAC via a usb C to usb converter.

AND BAM ! The resolution is stunning. I would equate it to a $5K upgrade in any part of my chain. It is truly an ear opener.

What did this ?

The USB C ?, The MacBook isn’t doing anything but output the data to my USB DAC.

I would love to hear from any of you who might know the reason for this wonderful improvement.

My primary guess would be that the newer Mac has a newer OS with improved drivers for the DAC, and that what you were using before was "crippled" relative to the driver. 

Either that or you find the effect of using a hub between your Mac and DAC to be euphonic and pleasing.  Just in general, USB hubs are not recommended for use with DACs, so you might want to connect directly.  

Hey @ BTW....if y'all are deep into your 'phile items, DIY'ing a 'puter isn't as deep a chore as one is already with your gear....more or less....

Pick your processor and match the m/b to it....select the suitable RAM chips, and stuff the slots FULL.
You want speed...there's charts online to guide that... ;)

Start 'fresh', you'll want your current lap or box for info and guides.

T-drives are ridiculous cheap lately.....but use a SSD drive for C:

There's audio cards available now that I couldn't afford or didn't exist at the time.

Find one...not just for 'now', but for Later,

What and to what to 'out' to is potentially another rung on the upgrade spiral....

Case in point:

Studios have been in digital for awhile now, with some analog diehards still in the mix.....

You Can't Beat Them...."Surrender!   ...but don't give yourself away..." ;)

Strip all the BS from Win 10 Pro....11's got 'issues', in mho.....and can be downloaded cheap....and you can keep it, and register it.

We're AMD fans here....Intel is too big, and we're underdog types.... *g*
